Specification of Letters Patent.

Application led May 20, 1910. Serial No. 562,530.

To all whom it may concern.'

a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Package-Forming Machine, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a raisin weighing, packing and carto-n filling machine, and its object is to weigh definite quantities of loose raisins, place a wrapper around the quantity of raisins weighed, close the wrapper over the raisins package and insert the package in an open carton. All the folding and packaging mechanisms being set in motion by the weight of the body'of raisins to be packed.

A further object of the invention is to produce a machine which will be operated by power merely upon the necessary quantity of material being placed upon the platform.

Another object of the invention is to produce a machine for weighing and packaging materials which do not readily form packages of themselves, but which must be pressed into -a package.

Another object of the invention is to produce a machine which is capable of using one strip of paper to Wrap the mass of fruit in, the paper being cut into suitable pieces and passed entirely around the package, or separate sheets may be used i-n the machine if so desired.

, Other objects of the invention will appear as the description proceeds.

In the drawings in which the same numeral of reference is applied to the saine portions throughout the several views, Figure l is a side elevation of the machine, Fig. 2 is a plan view of the machine, Fig. 3 is an end elevation of the machine looking from the right of Fig. 2. Fig. 4 is an end elevation of the machine looking from the left of Fig. 2. Fig. 5 is a vertical sectional view through the package feeding plunger and weighing chamber. Fig. 6 is a side elevation of the folding mechanism showing the weighing table support S remove from the machine. Fig. 7 is a view in section on the line 7--7 shown in Fig. 6, a

portion of the guide flanges on the side plate 3 being shown.

c It will be understood by those skilled in the art that it is quite ditiicult to weigh and package raisins or other sticky fruit of this character, for the reason that the pieces of fruit become gummed to the ortions of the weighing machine, or portions of the packaging machine with the result that the apparatus is quickly thro-wn out of commission. With this invention the fruit does not come into direct contact with anypart of the machine, save the feedin hopper, all other parts being covered by oiled paper Patented Feb. 4,1913.

which is wrapped about the mass of fruit.

naled.` These two side frames are secured together by means of a square frame 4 eX- tending across the top ofthe machine and in which the feeding hopper 5 is placed, said feeding hopper having a cored out portion 6. therearound to supply steam for heating the same. This feeding hopper has gates 7 and 8 operating in aslide 9. The .gate 7 is connected' to a lever 9 and the gate 8 is connected to a lever 10, saidlevers being pivoted at 11 and 12 respectively on the frame 4,.said

pivots having levers

13 and 14 connected therewith, a link 15 connecting. the

levers

13 and 14. Connect-ed to the lever 9, below the pivot point thereof, is a bar 16 havin a fork 17. i This bar 16 is connected with a bell crank lever 18 which is pivoted on the frame 4 at 19, said bell crank having a downwardly ext-ending bar 20 connected thereto. The bar 20 extends down from the bell crank lever 18 through an opening in the base of the machine and it is provided with a pin 2l for the purpose of opening the gates in the bottom of the feeding chute. The bar 16 operates to close said gates when a charge of fruit has been delivered to the packaging. apparatus in a manner to be explained later.

The weighing table 22 is supported by means of a long rod 23, which latter is in turn supported by the weighing lever 24, said weighing lever having a steel insert 25 to bear on the steel knife edge 26 to make the least possible friction therewith.

Extending outwardly from the machine at an angle of about 45 degrees to the horizontal, see Fig. lisa weight carryingpbar 24 on which the Weight 27 is supported, said weight being of such size as to move when the desired quantity of fruit has been placed on the weighing table. The bar 23 is pivoted to the Weighing table 2 2, and in order that the latter may move as easily and freely as possible in the compartment in which it travels, it is provided with four antifriction wheels 28, which are placed near the cent-er of the weighing table, and on the other two sides of the weighing table four anti-friction wheels 29 are journaled. The

eight wheels insuring the easiest possible movement of the weighing table, in the sage way in which it travels.

The weighing table moves from the position shown in Fig. 5 to the position indicated in dotted-lines below, in which latter position the body of fruit is formed into a package and has the oiled paper wrapping folded around the same.

Secured on' the

frames

2 and 3 are two arms 30 and 31, each supporting the roll of paper 32, said roll of paper having the sheet passing under a guide roll 33, journaled in the frame 4 above the

frames

2 and 3. From this point the paper passes between two rolls 34 apd 35 journaled on

shafts

36 and 37 respectively. The roll 34 being adjusted in its bearings by means of set screws 38 which regulate ythe pressure o-f the roll 34 on the paper. @ne of said rolls has a friction surface of cloth, rubber or the like.

pas-

The paper feed rolls are driven one complete t urn at a time by means of a gear 40 in mesh with the gear 37, the cycle of operations of which is to be explained later.

Journaled on the upper part of the frame 4 is a shaft 41 which is provided with a lever 42 connected to a link 43 which is raised by means of a roller 44 on the gear 40, said shaft 41 having two arms 45` at the free ends of which knife holders 46 are supported, said arms' being held in a fixed position by means of a small shaft 46. The knife holders 46 rest on flat springs 47, said flat springs serving to hold the knife in the raised position, after the paper has been cut. Attached to the knife holders 46 is a knife 48 which coperates with a fixed knife 49 to cut o6' the desired amount of paper required for each weighed quantity of fruit.

p Journaled in the

frames

2 and 3 is a shaft 50 which shaft has secured thereto a presser plate 51 which operates to press the oiled paper down on the body of the fruit and to form one side of the compartment in which the mass of fruit collects on said paper. This shaft is also provided with a crank 52 connected with a link 53 which latter is connected to an arm 54 freely movable on the shaft 55. The boss connected with said ipaaooe grooved' cam 57 on the shaft 58.- This grooved cam has a projection 59 which operates on the rotation of the shaft 58 to canse the presser plate 51 to move through an arc of 90 degrees, pressing the paper down against the body of raisins on the weighing table which latterl has then been forced by the weight of the fruit to its lowest position as indicated by the dotted lines on Fig. 5, the plate 51 immediately rising to its original position and being held there by the grooved cam 57.

Journaled in the

side plates

2 and 3 on the opposite side of the table from the shaft 50 is a shaft 60, and loosely journal'ed on the shaft 60 is the folder plate 61, said plate having upstanding slotted ears 63 at the oposite edges thereof. Keyed to said shaft 60 are two arms 64 which have a folding point 64 to complete, the operation of the folding of the paper around the ends of the package. Each arm 64 is provided with a pin 62 which extends through the slot in the ear 63, the object being to permit the arms 64 to move back out of the way of the incoming sheet of paper and to hold the plate 61 against the table from which the paper is fed over the weighing compartment. The operation of this folder will be rst, to press down on the paper and cause it to be pressed across the end of the package. When the plate Gltouches the top of the fruit package the arms 62 will continue their rotation until they have moved slightly more than 9() degrees, and have their points 64 extending across each end of the package tucking the paper down.

Immediately below the shaft 60 there is a shaft 67 also journaled in the side frames 2 and 3. This shaft carries rigidly therewith two tucking plates 68, each of which has a depending projection 69. These two tucking plates and the two tucking plates 64 cover about one-half of the end of the package and fold the top and bottom respectively of the paper across the ends of the body of fruit.

The frame 66, of which there is one slidable in each of the

plates

2 and 3 is provided with a projecting point 70 which covers the portion of the oiled paper package at the right hand edges thereof, see Fig. 1, between the two

plates

64 and 68. This plate 66 has an upwardly extending portion 7l which cooperates with the depending projection 69 on the plate 68 to raise the latter into contact with the plate 64 when the plate 66 has been pushed forward, a roller 71 lifting the arm 68 onto the portion 71..

Tt is to be noted that the folding mechanism is duplicated at each end of the formed package. This plate 66 is alsoy provided with teeth 72 which copcrate with the teeth on the boss 73 to push forward the final tucking plate 74. The plate 74 has a projecting pin 74 which operates in a slot in an arm 73 secured on the shaft carrying the boss 73. The plate 66 is pushed forward by means of a link 7 5 which is pivoted thereto and which is driven by means of a crank 76 on a shaft 77, said shaftcarrying .the gear 40 and a small gear 78 in mesh with the larger interrupted gear 79 on the shaft 80.

The shaft 80 is journaled in the

plates

2 and 3 and is parallel to the

shafts

77, 37 and 36. It will be observed that the* gear 79 has precisely the samenumber of teeth as the small pinion 78, the remainder of said gear being cut-away so that upon o-ne Vso rotation thereof the gear 78 will be rotated one complete turn only. It will also be observed that the gear 40 has the same number of teeth as each of the gears 36 and 37', the result of which will be to drive the

gears

36 and 37 one complete turn upon one rotation of the gear 40. Secured to the shaft 80 under the .gear 40 is a bevel wheel 81 which is driven by means of a bevel gear 82 on the shaft 58, said shaft being journaled in

boxes

83 and 84,' secured to the said plate 3 extending longitudinally thereof.

Immediately below the shaft S8-and parallel therewith is a shaft 85 journaled in boxes 86 and 87, said shaft having a gear 88'which has the same number of teeth as the gear 89, on the shaft 58. The shaft 85 carries a disk 90 having a pin 91 therein which is connected to a link 92, the opposite end of said link being co-nnected at 93 to a lever 94, said lever being pivoted at 95 to the base 1 of the machine. rlhe upper end of this lever 94 is pivotally connected to a link 96 which latter is pivotally connected at its opposite end to a plunger 97, said plunger havingubstantially 'the same cross section as the cross section of the package to be formed. This plunger 97 is movable in a slide box 98, which slide box note Fig. 5, is secured to the frame 3 at the same level as the top of the table when the package has been formed. Immediately opposite the plunger 97, the frame 2 is provided with an opening 99 through which the plunger pushes the package of fruit after the operations have been completed.

Secured on the base 1 and at a short distance from the plate 2 is a side plate 100 said plate having bearings for the

shafts

36 and 37, and for a shaft 101, which latter has a bearing 102 in the plate 2. This plate has a bed 103 with

grooves

104 and 105 therein, said grooves being for the reception ofchains 106 and 107, passing over

sprockets

106 and 107. Secured to these two chains,

- which are parallel to each other are a plurality of carton holding boxes 108, each of said boxes having two pins 109 to hold the iiaps 110 of the carton 111 open while moving through the machine. It will also be observed that the plate 103 is cut-away at 112 to permit the depending leaf 113 of the carton 111 to extend downward during the pas sage of the box through the machine, the upper leaf 114 of the box pressing against the side frame 2.

Since the empty packages are to be fed continuously to the machine by means of chains104 and 105, mechanism for moving one empty package into the vplace previously occupied by the filled package must be provided, and the movement must be accomplished during some time in which the plunger 97 is either stationary or moving away from the carton. Now, it will be observed that the paper feeding operation will be accomplished during the time in which the ends of the package are being folded, and before the plunger starts on its journey to press the package into the carton, therefore, the box must be moved during the period of rotation of either of the

rolls

34 or 35, and since the two shafts move in opposite directions, they form convenient means for discharging the cartons in one direction or the other, as may be desired.

The shaft 101 is provided with two sprocket driving gears 106 and 107 and on its outer end it has a gear 126 which is driven from a gear 127 on the projecting end of the shaft 36, or, if desired, from the projecting end of the shaft 37, the lat-ter gear being small enough to drive the

chains

104 and 105 just the distance from center to center of two cartons, the chain driving the gear 126 from the gear 127.

The Ashaft 58 is provided with a slidable collar 115, which collar has a clutch point to connect with the clutch 116 on the boss on the pulley 117. The slidable collar is operated by means o-f a lever 118 having a fork extending over the collar 115, said lever being pivoted to the frame 3 and 119. The opposite end of this lever has-a latch 120 pivoted thereto, the object being to throw the machine into gear when the bar 24 comes into contact therewith, and should the bar 24 accidentally pass the latch 120 it will permit the bar 24 to return to its initial position without interference.

The clutch on the collar 115 is provided with but a single point 121 which coperates with a single point 122 on the boss of the driving pulley 117. After the clutch has made one complete turn, the clutch is disengaged by the projecting point 123 on t-he boss of the pulley 117 striking an`oppositely placed point 124 on t-he lever 118 which forces the collar 115 away from the hub of the driving pulley and disengages the clutch.

In order that the bar 24 may not tip over on one side 0r move out of place, a slotted plate 129 is secured on the knife bar 26 by means of a set screw130 anda hole is drilled in this slotted plate to hold a ball 129 to bearon the side of the insert- 25 in said bar, one of these plates being placed on each side of said bar 24. lt will, of course, be understood that these balls touch the insert 25 very lightly'and offer practically no resistance to the movement of the bar 24, but do prevent it from mov'ing away from its proper position.

The cycle. of operations of the machine is as follows: Starting from the position of\ rest shown in Fig. 1, a piece of pa er having been placed under lthe hopper or feeding the fruit, the latter is permitted to fall on the paper, and` since the paper is very pliable, the weight of the fruit is immediately carried by the table 22 of the weighing apparatus and as the weight increases to such a point as becomes sufficient to raise the weight 27, the table22 descends to the bottom of the compartment in which it moves. As soon as. the bar 24 strikes the latch 120, and fork 17 both of which operations occur at substantially the same time, the machine is thrown into gear and will start when the points l121 and 122 meet, and the supply ofV fruit is cutfod by the closing of the gates 7 and 8. fThe machine is now running to form and fold the package. The first operation whichtakes place. is the throwing over of the roller 56 by theg high place of the cam 57. rlfhis causes the presser plate l51 which operates to fold one side of the paper down over the fruit toI firmly press the latter into the desired condition for insertion in the bok. This presser. plate is immediately returned to its initial position by the cam 57 and throughout the remainder of the cycle of operations this. plate continues in the same position. Now, it will be observed that the bevel wheel 82 during this time is driving the bevel wheel 8l lon the shaft 8O and the gear 79 is driving the gear 78, therefore, the slide 66 is in process of being pushed forward by the link 75. rfhe cam 71 on said slide pushing the folder plate 68 up during the same time that the plate 51 is pressing down on the fruit, thus the package is more conned at the ends thereof. As the slide proceeds on its course it successively engages the spur gear 7 3 on its lower side which latter pushes the folding plates 74 one half of the distance across the ends of the package and at the same time, the points on the slide have advanced one half the distance across the package from the opposite side thereof, and during this same time the teeth 65 engage the gear 65 and press the

folder plates

61 and 64 down on the package. --During the rotation of the shaft 77 the gear 40 is driving the

gears

34 and 35 one complete turn each time. The paper is fed across the intacte table under the feed hopper. and on the completion of the turn of the

rollers

34 and 35, the roller 44 strikes the lower end of the rod 48 and causes lthe -knife 48, to cut the paper. The spring 47 immediately4 returning the knife to the position shown in Fig. 1 after the'paper has been cut. The continued movement of the shaft 77 returns the folding apparatus to the position ini dicated in Fig. 1 and as soon as the shaft 77 is stopped in that position, the gear teeth on the wheel 89 -come into Contact with the teeth on the wheel- 88 and the latter is ro- \tated one complete turn, the link 92 pulling the plunger against the package and forcing :the fruit into the carton. The further gear 88 returns the plunger rotation of this .to the position s own in Fig. 3. v

1t will also be observed that the packages are moved forward one box by'V the chain 105 which is driven by the gear 127. As soon as the plunger has been withdrawn from its travelaoross the weighing table, the weight causes the latter to rise and the bar 24 strikes thepin 21 and opens the feed gates allowing the fruit to again collect on the paper placed vover the feed table. As soon as the shaft 58 has completed one turn, the projection 123 throws the clutch points .122 and 121 out of contact and the machine 95 remains quiescent during the time the fruit is again collecting on the weighing table. rEhe cycle being carried out as often as a certain weight of fruit is placed on the weighing table.
